4 Claims. (Cl. 183-2.?)

This invention relates to the separation and washing of gases from crudeoil.

An object of the invention is to provide simplified improvements inapparatus for the separation of gas from crude oil.

Another object of the invention is to provide improved apparatus of thecharacter described whereby the separation of gas from crude oil may beaccomplished in a substantially continuous operation.

More specific objects and advantages of the invention will appear and bebrought out more fully in the following specification, reference beinghad to the accompanying drawings wherein:

Fig. l is a side elevation view of a gas washing unit embodying myinvention.

Fig. 2 is an end elevation view of the same.

Fig. 3 is a sectional elevational view taken along the line 33 of Fig.2.

Fig. 4 is a partial sectional elevational view taken along the line 44of Fig. 3.

Fig. 5 is a partial View showing a portion of the apparatus partly insection, also seen in Figs. 1 and 2.

Fig. 6 is an enlarged sectional view taken along the line 6-6 of Fig. 3.

Fig. '7 is a partial perspective view as seen from the line 1-'I of Fig.3.

Referring more particularly to the drawings, I show a main separationtank Ill supported on a suitable framework 2 l, and a gas collector tankl2 suitably mounted above tank I and having a passage connection l3therewith which extends into and through the top of tank [0.

A crude oil inlet pipe 14 leads through a valve l into the upperinterior portion of tank it by pipe 18 which has a closed end H and aplurality of discharge slot openings it, as shown. A plurality ofcollector and deflector plates 20 are secured as by welding or otherwiseto pipe [6 between slots 18, plates 20 being inclined, and each plate 20has a parti-circular drip formation 2| adjacent but spaced from end wall22 of tank 10. Plate formations 2| each have a parti circular notch orcut-out portion 23 by which the separation of the liquid crude oil isfacilitated.

A pipe 24 extends through an end wall 25 of tank 10, and has a pick-upinlet 26 within tank I0 and above the bottom 2? thereof and leadsthrough a valve 28 to an oil outlet pipe 30. Tank ID has an accessopening 3| provided with a suitable closure 32, and a ball float 33 issecured to a lever 34 which has a bearing mounting 35 in closure 32, asuitable indicator 36 being operatively associated with lever 34.

Tank I2 is provided with a safety valve or plug 31 and a dome 38 towhich is connected a gas discharge pipe 40 having a pressure indicator4| which leads to a collector chamber 42. Chamber 42 is provided with avalved bleeder pipe 43. Chamber 42 has a gas discharge outlet 44provided with a valve 45, and a by-pass pipe 46 leads from chamber 42through a regulating valve 41 and connected to discharge outlet 44. Aplurality of downwardly directed parti-circular deflectors and bafiies4B are positioned across the opening of passage connection I3.

The operation of the invention should be apparent from the foregoingdescription. The gas laden crude oil is introduced through pipe I6 intotank I 0 and discharges therein through dis charge openings I8, and theliquid oil accumulates at a level indicated at 49 which is shown byindicator 36. Tank I0 is provided with a sludge discharge opening 50 anddischarge pipe 5| provided with a valve 52. The gas which is freedwithin tank I0 is conducted through passage I3 into tank l2 and thencethrough pipe 40 and collector chamber 42 to the outlet 44, eitherdirectly or through by-pass 46. As the gas and oil mixture passesdeflector plates 20, a considerable amount of oil is separated andcollected thereon due to the reduction in speed of flow, and most of thegas and oil separation occurs in this portion of tank It). Whateveradditional oil is carried with the gas through passage [3 is collectedand separated by baflies 48, which oil is returned to the level 49.

Having described my invention what I claim is:

l. A gas washer as described, comprising in combination an elongatedhorizontal separating tank having a crude oil inlet, an oil outlet and agas outlet, said inlet comprising a horizontal pipe extending into thetank a substantial distance and having a plurality of openings in thelower portion thereof, a plurality of inclined deflector plates; onebelow each of said openings and terminating adjacent a wall of the tank,the lower edges of said plates having flanged dispersion dripformations.

2. A gas washer as described, comprising in combination an elongatedhorizontal separating tank having a crude oil inlet, an oil outlet and agas outlet, said inlet comprising a horizontal closed end pipe extendinginto the tank a substantial distance and having a plurality of openingsin the lower portion thereof, a plurality of inclined deflector plates;one below each of said openings and terminating adjacent a wall of thetank, the lower edges of said plates having Number flanged dispersiondrip formations. 1,513,354 3. The combination according to claim 21,710,178 wherein the gas outlet is positioned in the top of 1,73%,880the tank and displaced horizontally a substan- 5 1.916,065 tial distancefrom the inlet. 2,054,124 4. The combination according to claim 22,151,863 wherein the outlet has a plurality of baffle plates.
